Hi, JHPJHP!

I think it will be more compact code using OpenCV (but more dlls).

P.S. I deleted my message so that it no interferes with your news. :)

I was more referring to automation; instead or in addition to the user adding points to create Vector Curves, the process could be automated.

See animated GIF below (created using Video Snipping Tool):
1. Downloaded a detailed image to be used as a template for our Vector Curves.
2. Opened the existing OpenCV example making a single change to the code.
3. Opened the previously downloaded image; all points were ready to be processed or turned into Bezier Curves.

Hello JHPJHP,

Nice to have you back here ...

For my new robot, I did something totaly out of my budget,
I just brought a LattePanda alpha with Win 10 pro installed.
So, now (at last) I have the best/fast processor card to run PB and my robot ...

Finely I like to start and install all the needed software on this board.

Q1)
What is the minimum software I need to install to run your Open_CV with PB 5.72 LST x64,
I want to use 2 camera's for obstacles detection (red soda cans).

Q2)
Do you have any experience for what camera to use ?

greetings,
marc

Hi Marc

Are you familiar with DF Robot?

Thank you... if/when I find the time, I'll craft :) together something to better showcase what I am envisioning.

-----------------------------------------

Hi marc_256,

Thank you. I was hoping to hear that you were able to merge your robotics with PureBasic. Congratulations :!:

Deciding on which algorithms you require will determine which DLL's you need; no installation required.

The basic requirements for the webcam are:
- opencv_core2413.dll, opencv_core2413.lib
- opencv_highgui2413.dll, opencv_highgui2413.lib
- opencv_imgproc2413.dll, opencv_imgproc2413.lib

Any relatively new webcams will work. It's more about how well you write your code that will determine the accuracy and speed for identifying objects.

Good luck, and if you need any help with the code or just deciding the best algorithms, drop me a post.

Hi,
i just found this interesting topic and that might be interesting.
I would like to save images from a webcam and then analyze them in order to implement a kind of target tracking.
Is that possible with it?

Unfortunately I have not been able to test the program so far because the download does not work!

greetings

wolfgang

Hi derschutzhund.
Yes, it's possible to save image from webcam. Moreover, you can analyze every frame from webcam in realtime if your analysis does not take too much time. There was many examples in the "PureBasic Interface to OpenCV" pack.
